It is important to elicit what patients mean by IMF. Intermittent fasting, sometimes called intermittent energy restriction, is an umbrella term used to describe dietary regimens involving energy restriction for specific periods of time. Mattson and colleagues define IMF as "eating patterns in which individuals go extended time periods (e.g., 16–48h) with little or no energy intake, with intervening periods of normal food intake, on a recurring basis" (1, 2). Time-restricted eating (TRE) is a specific IMF paradigm involving consistent fasting and eating periods within a ...References1. Mattson MP, Longo VD, Harvie M.
